Justin Lebar 1eac5948db [CUDA] Add -fcuda-allow-variadic-functions. 
Summary:
Turns out the variadic function checking added in r258643 was too strict
for some existing users; give them an escape valve.  When
-fcuda-allow-variadic-functions is passed, the front-end makes no
attempt to disallow C-style variadic functions.  Calls to va_arg are
still not allowed.
